In 2025, the contiguous U.S. experienced its fourth-warmest year on record and 23 billion-dollar weather and climate disasters, totaling $115 billion in damages. Globally, 2025 was the third-warmest year since 1850, with NOAA data indicating it was approximately 1.3°C warmer than the pre-industrial average. The year was marked by record-breaking December heat in the U.S. Southwest and devastating atmospheric river flooding in Washington and Oregon.
